3-568DS1-BD (DS1 Interface Circuit Pack)
3
FAIL DS1 Interface circuit pack detects a Loss of Signal alarm. The physical link is
broken or the remote DS1 endpoint is down. All trunks or ports of this DS1
interface circuit pack are out-of-service. If the DS1 Interface circuit p ack is
designated as the supplier of the system synchronization source, then the
system synchronization maintenance will adopt a source elsewhere. Refer to
"SYNC (Synchronization)" section for details.
1. If the DS1 Interface circuit pack connec ts to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 Interface
circuit pack connects direc tly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
2. Check the physical connection of the DS1 Interface circuit p ack and the
cable. If a 120A1 CSU Module/T1 Sync Splitter is physically connected to
a TN767E board on the back of the port carrier, check the physical
connection of the CSU Module/T1 Sync Splitter and make sure the
Network Interface cable is plugged into the CSU Module’s/T1 Sync
Splitter’s NETWORK jack.
1300 FAIL The CSU Module or the T1 Sync Splitter is missing. The
Near-End CSU Type
field on the
add ds1
form has been administered as
integrated
but the 120A1
CSU Module/T1 Sync Splitter is not physically connected to the TN767E board
on the back of the port carrier.
1. If using the 120A1 CSU Module/T1 Sync Splitter, plug the CSU Module/T1
Sync Splitter into the TN767E circuit pack’s connector on the I/O
connector panel on back of the carrier. Otherwise, change the
Near-End
CSU Type
field using the
change ds1
form to
other
.
2. Run the test again.
1301 FAIL The 120A1 CSU Module or the T1 Sync Splitter is physically connected to the
TN767E board on the back of the port carrier but the
Near-End CSU Type
field
on the
add ds1
form has not been administered as
integrated
.
1. If the 120A1 CSU Module/T1 Sync Splitter is to be used, use the
change
ds1
command to change the
Near-End CSU Type
field to
integrated
.
Otherwise, physically remove the 120A1 CSU Module/T1 Sync Splitter
from the back of the port carrier.
2. Run the test again.
1302 FAIL Attempting to use the 120A1 CSU Module with a TN767E circuit pack that is
configured for 32-channel (2.048 Mbps) operation. The CSU Module only
works with a DS1 board configured for 24-channel (1.544 Mbps) operation in
the United States of America.
1. If the 120A1 CSU Module is to be used, physically remove the TN767E
circuit pack and reconfigure for 24-channel (1.544 Mbp s) operation.
2. Reinsert the circuit pack and run the test again.
